US politician caught deserter at end of rally (8)
I believe the answer is:
democrat
'us politician' is the definition.
(I've seen this before)
'caught deserter at end of rally' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'deserter' becomes 'rat' (I've seen this before).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'end of rally' becomes 'demo' (I am not sure about this - if you are sure you should believe this answer much more).
'c'+'rat'='crat'
'crat' put after 'demo' is 'DEMOCRAT'.
Can you help me to learn more?
(Other definitions for democrat that I've seen before include "Believer in government of, for and by the people" , "One advocates government by the people's elected representatives" , "American politician" , "US politician" , "Member of US political party" .)
